I have an ASUS K55VM and it came with DOS, and then Windows 7 was installed. I am planning to install Ubuntu on it. My computer had 4 partitions: 240GB, 230GB, 230GB, and 230GB, and I changed this to 5 partitions: 243GB, 230GB, 230GB, 150GB, and 80GB. I installed Ubuntu 12.04 to the 80GB partition through a USB flash drive. It installed fine, however the problem is during the Boot option in Windows Boot Manager. When I choose Ubuntu, this what is displayed:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart your computer. 2. Choose your language settings, and then click "Next," 3. Click "Repair your computer." If you don't have this disc, contact your system administrator or computer manufacturer for assistance. File: \ubuntu\winboot\wubildr.mbr Status: 0xc000000e Info: The selected entry could not be loaded because the application is missing or corrupt.
I tried to change the boot option for the OS and made Ubuntu as my first option. It worked, however Windows 7 does not show up in GRUB. In this fear I did the following:
- Restarted my PC changed boot option 1 to Windows.
- Formatted the drive to which Ubuntu was installed (80GB one) through Windows.
- Restarted again.
The problem persists. Windows Boot Manager still shows Ubuntu, and when I choose this it gives two lines one like:
grub rescue>, but my Windows 7 is working perfectly fine.
Now I want a solution to remove Ubuntu from the Windows boot option and reinstall completely.
